Activision revealed that its flagship franchise, Call of Duty, earned $1 billion in just 16 days proving that 18-35 year old males with disposable income are willing to shell out serious bucks for loud violence.

Since it's a good possibility that Call of Duty: Modern Warfare 3, which went on sale on Tuesday at midnight, will become the best selling video game of all-time, it probably shouldn't come as any surprise that it'd be out of stock in some places for the first week or so of its release.
